FYI, I got 5 of the SiPolar-esques in recently. I still have to try it, but all 20 ports at least boot up fine on my model (haven't plugged it into a PC quite yet).

yea anker was my first choice but they seem to be sold out on amazon 
It's probably our fault they are sold out. i think we blind sided them.

can you guys recommend to me a reliable 10 port hub that i can purchase to power 10 usb block eruptors im having a hard time finding one on amazon
If you are not dependant on Rpi, choose one of the USB 3.0 hubs. Anker was getting pretty good reviews. See the table in the OP, with the corresponding footnotes.

Yeah I got the original response as "900ma" ... then I asked what does it specifically state on the plug itself.. and got that slightly odd 5V9A answer...
July 31, 2013, 12:36:26 PM
sorry im terrible at these types of calculations so if the math is correct this is a good hub to purchase possibly or no?

Unless it's like their 10 port usb 3.0 hub which has a charger port
IF that's the case:
1 charger port at 1.5 A = 7.5 Watts
3 3.0 High power port at .9A (900 mA) = 13.5 W
9 USB 2.0 ports at 533 mA = 24 watts
For a total of 45 W
IF that's the case:
1 charger port at 1.5 A = 7.5 Watts
3 3.0 High power port at .9A (900 mA) = 13.5 W

has anyone ever tested out this hub? http://www.amazon.com/Juiced-Systems-USB-3-0-2-0/dp/B00B1WMYGO
I noticed that one too.. got a mix of USB 2.0 and 3.0... wouldn't work with the Pi right?
according to the specs on their site:
\\
4 Upstream and down stream USB 3.0 ports. 9 Upstream and down stream USB 3.0 ports. 480mpbs and 5gbps transfer rates with on/off LED indicator with power switch for each port. Supports hot swap plug and play devices.
**Does not need power supply to operate but recommended for high power consumption devices**
Hub weight: 140g
Cable Length 100cm
Power Supply 3.5mm DC 5v jack.
//
Can't find the Amps..
yea i couldnt either
Speedy response back from the company contact on their website... states the following:
"I believe, the units are as follows : 5 Volts , 45 Watts 9 Amps - 900mA each USB port."
I emailed them and got the same response. But is it just me or does the math not work out?
This is my assumption util I hear back further from them. There are 13 ports. USB 3.0 has 3 power configurations, low power, high power, and charging only. Assuming the 4 USB 3.0 ones are high power, that/s 900 mA each or 18 Watts. That leaves 27 Watts of power remaining split among the 9 remaining USB 2.0 ports. At 5 volts a piece, that's 600 mA per port (which is a bit higher than the standard of 500mA so I don't know why they would do that).

I have a better idea... Not sure if anybody mentioned this before:
Take a cheap-o USB-hub, 5V power supply, grab a soldering iron, take the USB hub apart, disconnect power wires from the entering USB port, solder these to the power supply output, re-assemble -- bang! You've got yourself a <$10 powered USB hub.

I think the highlighted part, would be where most (including myself) start scratching their heads.
Using Solar power, if you have it in abundance is great - would truly make bitcoins "sent from above"
I can build raspberry pi/cubieboard or marsboard based rigs for anyone in Poland, providing that they pay for components and shipping.
...Apart from that, I'm gonna make a step-by-step video tutorial for people who are interested in modding a cheap USB hub to be powered.

This is precisely the approach I will be taking with my RPi... Except for the fact I have designed a custom board with li-ion battery and small solar panel.
EDIT: I also have 2 other boards worth testing. These puppies are fully compliant with USB 2.0 specs.

I don't have more information, than what is stated in the paragraph above the chart: USB 3.0 hubs will not work with Pi, while all USB 2.0 hubs *should* work.
D-Link DUB-7 will definitely work according to several reports in the thread, not sure about the other hubs.

Is there anyway that you could modify the master chart to add Raspberry Pi compatibility? It'd be nice to simply look at a glance to see if a particular hub will work with Raspberry Pi.
As an off topic note, I think its time for a newer Raspberry Pi with USB3! lol
